ChatGPT :
When someone describes a political party as "arrogant and incompetent," it means that they believe that the party is both overconfident and lacking in the ability to effectively govern or carry out their duties.
The use of the word "arrogant" implies that the party is excessively self-assured and perhaps overly confident in their abilities, to the point where they may ignore the needs or opinions of others. On the other hand, the word "incompetent" suggests that the party is not capable of doing what is required of them, either due to a lack of skill or knowledge, or a failure to prioritize important issues.
Overall, this description suggests a negative view of the party's ability to govern and suggests that the speaker does not have much confidence in their ability to lead effectively.
